<P>PROBLEM TO BE SOLVED: To provide an ion exchange filter capable of obtaining an ion exchange filter having a high ion exchange efficiency or an ion exchange filter having a low pressure loss in accordance with a fuel cell system. <P>SOLUTION: The ion exchange filter is provided with a case 13 having an inlet 14 and an outlet 15 of fluid and two kinds of cartridges 11, 12 which are exchangeably disposed inside the case 13 and have packed an ion exchange resin therein. By exchanging at least two kinds of the cartridges 11, 12, an ion exchange filter attaching importance to the exchange efficiency, which has a high pressure loss and a high ion exchange efficiency or an ion exchange filter attaching importance to the pressure loss, which has a lower pressure loss than the ion exchange filter attaching importance to the exchange efficiency and a low exchange efficiency. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
